Y' To all wlion) i-ztmay concern {Be it known fthat 1I,-WALTER gI. Wesens, a citizen of fthe'United States, residing at Los Angeles, in I-the county-of Los Angeles and State of California, have invented a new and useful Computing fDevice, of which f the `following -is a specification:

b This inventlon relates to a" computing device !for calculating the vprobabilities or relation`s of associated classesI of data, for example, ,exchangeable lists, scales, charts or tables','or portions orlcombinations thereof, such as those .giving multiples or fractions of base rates .of Wages, interest, rents, valuations, incomes, taies or insurance;.or thosepresenting computations, reports or 'statistics of production, lconsumption, .costs depreciation, values, prices, discounts,

' profits, 'losse's, sales,- purchases, weights,fcontents, distances, speed, fuel consumption, time, stock tluctuations,'imports or exports; or schedules of passenger fares,"freight `charges,express tariffs or lpostage-rates. v

The invention -`is herein illustratedcas aps piied to'theV computation ,of handiccpsffor -Ar'ace horses it will be understood thatfby suitable l modifications in, the vdata -fgures on the several 'elements of the dvicat may be adapted lto other computations,

rThe' main object Cof vthe invention is to supplge means whereby Vsuch :computations may" made quickly 'bya process of mehanica'l operation 'and inspection, as 'flistinct `fromf mental calculations.

A'urther object of the 4invention to providel means whereby` a large :number of computations of intricate character may ,'be

madequickly and easily. V

Other objects of the-invention will appear hereinafter..` Q,

The accompanying drawings 'illustrate an.

embodiment of '-my `invention, and ,referring thereto: Figure l is aront elevation ofgthe device, the inclosing-case being shown open to expose the computation means. Fig'. 2 is an end elevation of the i;nclosing case Lin closed position. Figi -3 'is a vertical-section of the device. Fig, 4 is an endelevation ofV theda'tadrum. l

The device is mounted in a suitable case 1, provided with anfopening 2, and having'a cover 3, hinged to the case at fi,- and adapted to close said opening.` -Within the case 1,-

is mounted a drum 5, carried by a shaft 6, mounted toturn in bearings at the ends of the casing 1, and` provided vvlth operating '-marksQrepresenting the times in which the courses maybe traversed, in minutes, sec- -0nds,a1idfifth-seconds. 'Below said Aslot 10 is `a strip `12, vcarrying a vseries of numbers Vor marks ida-corresponding *to other, data 'entering into thecomputations, or in tlie particular.case-here shown, corresponding to handicap "\points; Below this strip 112, is :mounted a sliding -correction scale 1 4, yslidable longitudinally lin guidew'ay *15,* so as to bring:zr-pointerfor index 15,', on vsaid. slide, Iopposite any one of the point -marks' 13, on the strip d2. `Said slide' is, in the presentcase, provided with anrupper row'o numbers v7indicated at v19, their intervals corresponding !to those of the arbitrary points.

on 'fthe lined scale, and representing horse lengths or one-fifth secondsg-and the lower numbers indicated at 20 corresponding 'to excess or deficiency of pounds carried -by the horse. Said slide 14, is provided at one or both Aends with up-turned lugs at 2'3", to facilitate lmanipulation of the slide. These marks 20, corresponding 'to Weight, ,ma be'v spaced uniformly as 'shown at the -left o the index 15,-0'1' xthey fmay be spaced at progres- Sively increasing intervals, as shown at` the l right o'f said index, so as Eto prov-ide for an increased proportionate allowance for large excess-of weight.

[n using lthis computing device ffor predieting 'the position of a horse at 'the finish of a coming race, suitable scales, tables, or charts (form sheets) are used in connection with the device. '.These published records er form sheets give the distance traversed, the names of the contending horses, the wei hts carried by each, their order at the ics linie thel distance in lengthsl which each beat the next behind him, and the time inv minutes, seconds, and -fths of afsecond in which the race was beaten. In predicting.
